Fix corner cases in protocol detection and connection cleanup

- Fix double-resolve race in probeTS3Query (data event vs connect timer)
  by guarding with a resolved flag
- Fix double-resolve in probeTS6HttpQuery similarly
- Support custom query ports in detectServerProtocol via DetectOptions
- Clean up httpQuery and detectedProtocol on disconnect()
- Add res.on("error") handler in HTTP Query client to avoid unhandled errors
- Improve logging: warn with actionable message when protocol is unknown
